FASTENING DEVICEEOR sHoEsf SPECIFICATION forming part of Letters Patent No. 244,534, dated. July 19, 1881.

Application filed June ,1, 1881'. (Model) To all whom it may concern Be it known that I, SAMUEL G. BLAOKMAN, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Fastening Devices for Shoes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyin g drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a top or plan view of the fastening, the two members being locked together. Fig. 2 is a longitudinal section taken on line a: 3 Fig. 1, the parts being in the same position as they are in that figure. Fig. 3 is a section taken on same line, showing the members disconnected from each other. Figs. 4 and 5 are perspective views-detached, of two members forming parts of my device.

In the drawings, A is one member, consisting of two side bars, a a, an end bar, a, and. two bars, a a the end bar, a being made, by preference, curved or angular in cross-section, for a purpose which will soon'be explained.

a at are spurs or tangs projecting from end bar, a, and adapted to be thrust through the material to which the member A is to be applied and then bent over, or a washer with suitable openings may be used upon the under side of the material to receive the ends of the tangs. The bar a is not round in cross-section, but is irregular in form, preferably triangular, as shown, for a purpose which will soon be explained.

Bis a locking-lever mounted on the bar a This lever is made of some elastic material, preferably spring brass or steel, and has a seat, I), which conforms substantially to the surface of the bar a. As shown, said lever is made from a single strip or sheet of brass doubled back upon itself, both legs being of substantially the same length; but, when preferred, one leg maybe made much shorter than the other, or it maybe made to only surround the bar a on which it is mounted, the part b of the lever being curved or arched in order that it may fit over a curved end bar, which is to be described. From an examination of Figs.

2 and 3 it will be readily understood that when the lever is placed in either of the positions there shown it will be locked to its supporting end bar with sufficient firmness to prevent accidental displacement.

C is .another member having an end bar, 0,

provided with one or more spurs or tangs, c,

adapted to secure the member to the material upon which it is to be used. c c are side bars, and c c c are cross-bars, forming a series of slots to receive the -lockingdever, these crossbars being also preferably curved or angular in cross-section, whereby their under surfaces are adapted to fit over and be interlocked with the end bar, a of the member A.

In using this fastening the lever Bis placed in the position shown in Fig. 2, and then inserted in one of the slots of the member C, after which said lever is turned down into the position shown in Figs. 1 and 3, when the two members will be firmly locked together.

This fastening is designed more particularly for use upon that classof overshoes which are known as arctics; and it will be seen that by reason of the member C being provided with a series of slots the shoes can be taken up around the ankles, as circumstances may render desirable.

It will be readily understood that the interlocking of the bars a c facilitates the holding of the members A C together by the lever B, and that the curved portion b of the lockinglever permits the lever to occupy a position substantially parallel with that of the member A when the parts are placed as shown in Figs. 1 and 3.

It is apparent that the bar a might be made in other irregular form-that is,in some other form which is not round, and yet secure the eccentric action upon which the lever depends the two members A G with a locking device;

but my construction is more simple than any other of which I have knowledge.

What I claim is- 1. The hereindescribed fastening device,

consisting of the member A, having the bar in cross-section, corresponds to said bar, sub- 10 a polygonal or elliptical in cross-section, and stantially as set forth.
